- NEFX (extension: “.nefx”); merged pixel shift files, which are generated by using NX Studio to merge image files recorded using pixel shift on the camera
- MPO (extension “.mpo”)
Caution: HEIF Pictures
HEIF pictures may no longer be viewable in the view area after being edited in other applications.
Viewing RAW Pictures
In the case of RAW pictures edited using plug-ins in the Nik Color Efex Pro series or created or edited using optional Picture Controls not installed with NX Studio, NX Studio will display only the previews embedded in the images, not the pictures themselves. Editing and export are not supported.
HEIF Pictures with Thumbnails Marked 
NX Studio cannot be used to edit HEIF pictures with thumbnails marked (0 Photo Thumbnails).
- Pictures shot in HLG on cameras that support tone-mode selection are recorded in HDR. Here “HDR” (high dynamic range) refers to an imaging technology that supports a range of tones (dynamic range) wider than is offered by existing techniques, as distinct from multi-exposure HDR capture, a high-dynamic-range imaging (HDRI) technique that blends multiple still photographs shot at different exposures. Pictures taken with SDR selected for tone mode are recorded using the standard dynamic range (SDR).
| Camera tone mode | Image file formats | Dynamic range |

- Tones in pictures recorded in HLG on cameras that support tone-mode selection will not display correctly when viewed on monitors that are not HDR-compatible.
